It's a cheapie treadmill that seems to have been discontinued. The model is Proform Crosswalk 400E.
Based on my experience, I'm guessing any kind of treadmill would work as long as it has a regular sized belt. You want to have enough space behind the "desk", otherwise your feel will be falling off the back of the treadmill when you walk.
